IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE,

ELECTRICAL SHOCK, OR INJURY TO PERSONS

READ AND FOLLOW ALL INSTRUCTIONS

SAVE THESE INSTRUCTIONS

WARNING: When using electrical products, basic precautions should always be followed,

including the following:

WARNING: Risk of personal injury. Do not permit children to use this unit unless they are

closely supervised at all times.

WARNING: Risk of personal injury. To avoid injury, exercise care when entering or exiting the

bath.

WARNING: Risk of electric shock. Do not permit electric appliances (such as a hair dryer, lamp,

telephone, radio, or television) within 5’ (1.5 m) of this bath with airjets.

WARNING: The use of alcohol, drugs, or medication can greatly increase the risk of fatal

hyperthermia. Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs

when the internal temperature of the body reaches a level several degrees above the normal body

temperature of 98.6°F (37°C). The symptoms of hyperthermia include an increase in the internal

temperature of the body, dizziness, lethargy, drowsiness, and fainting. The effects of hyperthermia

include: (a) failure to perceive heat, (b) failure to recognize the need to exit the bath, (c)

unawareness of impending hazard, (d) fetal damage in pregnant women, (e) physical inability to

exit the bath, and (f) unconsciousness resulting in the danger of drowning.

An equipment grounding terminal is provided in the ﬁeld wiring compartment. To reduce the risk of electric

shock, this terminal must be connected to the grounding means provided in the electric supply panel with a

conductor equivalent in size to the circuit conductors supplying this bath with airjets.

A pressure wire connector is provided on the exterior of the blower motor or control within this unit to

permit connection of a bonding conductor between this unit and all other exposed metal in the vicinity, as

needed to comply with local requirements.

Use this bath with airjets only for its intended purpose as described in this manual. Do not use attachments

not recommended by Kohler Company.

Never drop or insert any object into any opening.

The bath must be connected only to a supply circuit that is protected by a Ground-Fault Circuit-Interrupter

(GFCI) or Residual Current Device (RCD). Such a GFCI or RCD should be provided by the installer and

should be tested on a routine basis. To test the GFCI or RCD, press the test button. The GFCI or RCD should

interrupt power. Press the reset button. Power should be restored. If the GFCI or RCD fails to operate in this

manner, the GFCI or RCD is defective. If the GFCI or RCD interrupts power to the bath without the test

button being pressed, a ground current is ﬂowing, indicating the possibility of an electric shock. Do not use

this bath. Disconnect the bath and have the problem corrected by a qualiﬁed service representative before

using.

Do not allow the water temperature in the bath with airjets to exceed 104°F (40°C).

Hydro-massage action can cause even a small amount of bubble bath, bath soap, shampoo, or bath oil to

foam excessively. For this reason, please do not use these products during blower operation.

Your new Kohler bath with airjets has been listed by Underwriter’s Laboratories, thus ensuring safety for

you and your family. Your new bath also conforms to rigid ANSI and IAPMO standards set within the

plumbing industry.

Care and Cleaning

Do not use powdered cleaners unless the cleaner is fully dissolved in water. Solid substances

could block the airjets.

Do not use full strength bleach or ammonia cleaning solutions. Chemically active cleaning

solutions can damage the bath surface.

Do not use abrasive cleansers or solvents on acrylic surfaces. Abrasive cleaners and solvents can

damage the bath surface.

Wipe out your acrylic bath with a soft cloth after each use.

Avoid detergents, disinfectants, or cleaning products in aerosol cans.

NOTE: To restore dull or scratched units: Apply white automotive polishing compound with a clean rag.

Rub scratches and dull areas vigorously. Wipe off residue. Follow with a coat of white automotive paste

wax. Do not wax areas where you walk or stand.

Cleaning Your User Keypad and Remote Control

Use a soft cloth to wipe the keypad and remote control after each use. If the surface becomes dirty,

use a non-abrasive soap and warm water to clean.

Maintaining the Airjets

If cleaning the airjets is required due to hard water deposits, use a small between-the-teeth dental

brush and white vinegar. Dip the brush in the vinegar, brush the hole, rinse the brush in clean

water, and then use the wet rinsed brush to rinse the hole.

Fill the bath with water to the top row of airjets. Drain the bath and press the purge button.
